conferenceObject Waiting List Risk Factors in Pediatric Heart Transplant Center in the Developing Country(2012) CAUDURO, A. S.; MOREIRA, L. F. P.; TANAMATI, C.; CANEO, L. F.; PENHA, J.; JATENE, M. B.Purpose: Most of data upon waiting list risk factors are based in studies done in developed countries. In this study we aimed to identify what are these risk factors in a health system enviroment of a developing country like Brazil. Methods and Materials: Time on the waiting list was defined as the time of initial listing to the time of removal due a transplant, death, recovery or removed. Survival time in the waiting list was estimated using the Kaplan-Meier method. Univariate and multivariate relationships were evaluated with the Cox proportional hazards model. Results: Of 222 patients the median age was 3.9 yrs, median weight 13Kg; female 52%. Dilated cardiomyopathy 62%, congenital heart disease 25%, restrictive cardiomyopathy10%, chronic graft failure 3%. We had 45%listed as priority. 41% transplant, 40% died, 14% were removed, 5% are still waiting. Survival were 73% in 30 days, 60% in 90, 51% in 6m. Diagnosis, age, weight, urea, level and priorit status were considered predictors in the univariate analysis. Diagnosis of CHD and, priority status, were found as independent risk factors. Conclusions: Less has been known about the mortality risk factors in the waiting list in our enviroment. Actually these data are very similar to those ones retrieved in the early 1990 when the young and very ill children were destined to died. These results support the urgency of adoption of new technologies and new strategies addressed to child in the waiting list.- Evaluation of Surgical Treatment of Congenital Heart Disease in Patients Aged Above 16 Years(2012) CANEO, Luiz Fernando; JATENE, Marcelo B.; RISO, Arlindo A.; TANAMATI, Carla; PENHA, Juliano; MOREIRA, Luiz Felipe; ATIK, Edmar; TRINDADE, Evelinda; STOLF, Noedir A. G.Background: The increasing number of children with evolving congenital heart diseases demands greater preparation of professionals and institutions that handle them. Objective: To describe the profile of patients aged over 16 years with congenital heart disease, who have undergone surgery, and analyze the risk factors that predict hospital mortality. Methods: One thousand five hundred twenty patients (mean age 27 +/- 13 years) were operated between January 1986 and December 2010. We performed a descriptive analysis of the epidemiological profile of the study population and analyzed risk factors for hospital mortality, considering the complexity score, the year in which surgery was performed, the procedure performed or not performed by the pediatric surgeon and reoperation. Results: There was a significant increase in the number of cases from the year 2000. The average complexity score was 5.4 and the septal defects represented 45% of cases. Overall mortality was 7.7% and most procedures (973 or 61.9%) with greater complexity were performed by pediatric surgeons. Complexity (OR 1.5), reoperation (OR 2.17) and pediatric surgeon (OR 0.28) were independent risk factors influencing mortality. Multivariate analysis showed that the year in which the surgery was performed (OR 1.03), the complexity (OR 1.44) and the pediatric surgeon (OR 0.28) influenced the result. Conclusion: There is an increasing number of patients aged 16 years which, despite the large number of simple cases, the most complex ones were referred to pediatric surgeons, who had lower mortality, especially in recent years.

- The Impact of Tacrolimus as Rescue Therapy in Children Using a Double Immunosuppressive Regimen After Heart Transplantation(2012) BRANCO, K. C.; AZEKA, E.; TRINDADE, E.; GALAS, F. R. B.; HAJJAR, L. A.; BENVENUTI, L.; RISO, A.; TANAMATI, C.; PENHA, J.; AULER JR., J. O. C.; JATENE, M.Background. Organ transplant recipients with refractory rejection or intolerance to the prescribed immunosuppressant may respond to rescue therapy with tacrolimus. We sought to evaluate the clinical outcomes of children undergoing heart transplantation who required conversion from a cyclosporine-based, steroid-free therapy to a tacrolimus-based regimen. Methods. We performed a prospective, observational, cohort study of 28 children who underwent conversion from cyclosporine-based, steroid-free therapy to a tacrolimus-based therapy for refractory or late rejection or intolerance to cyclosporine. Results. There was complete resolution of refractory rejection episodes and adverse side effects in all patients. The incidence rate (X100) of rejection episodes before and after conversion was 7.98 and 2.11, respectively (P <= .0001). There was a 25% mortality rate in patients using tacrolimus after a mean period of 60 months after conversion. Conclusion. Tacrolimus is effective as rescue therapy for refractory rejection and is a therapeutic option for pediatric patients.
